What was studied

A historical dissertation concerning 31 school programs and 1,934 students, with 1,695 students in grades 9–12 forming the main analysis.

What it contributes

The work provides a period-specific view of selected programs and their procedures.

Where the evidence stops

The selected schools are not a statewide census. The design does not establish that a teaching practice caused achievement or explain present-day adult community band participation.
